I only know of three.
Volcanoes form:
(1) At convergent boundaries (subduction zones), where one plate is being subducted (going beneath) the other. At the right depth, it will begin to melt, and form new magma. This magma will rise, and can punch out of the overriding crust to form a new volcano. On land, this creates a volcanic mountain chain (the Juan de Fuca plate subducts beneath the North American plate and creates the Cascade Mountains). In the ocean, this will create a volcanic island arc (The Pacific plate subducts beneath the North American plate and creates the Aleutian Island Arc). In general, these volcanoes are more felsic ("granitic") in nature, and more explosive. These are usually stratovolcanoes/composite volcanoes.
(2) At hot spots, where a large magma plume has risen from the mantle (generally, but not always beneath oceanic crust) in the middle of a plate (away from a boundary) and has cut through the crust to form a volcano. Given time and enough erupting, it will rise through the ocean surface and emerge as a volcanic island - which is how the Hawaiian Islands and Hawaiian-Emperor Seamount range formed. These are generally shield volcanoes.
(3) At divergent boundaries, where the crust is moving apart, magma is wedging its way between the plates, and often erupts as a volcano. We just generally don't think of these because they're usually thousands of feet below the ocean, which most people don't care about. However, if you visit Iceland, you can walk up and see the divergent boundary of the Mid-Atlantic Ridge splitting the small country in two. When it gets angry, it throws beautiful, mile-long fissures of lava hundreds of feet into the air. That's definitely a volcano - a fissure volcano.

What are the two major ways in which volcanoes most often form?
volcanoes takes place in two ways which are at the hotspot and at the point of weakness which are fault or crack
What is the difference between Compare volcanoes that form on land with volcanoes that form in the ocean.?
Land Volcanoes eat lamas and underwater volcanoes eat camals
What are the two ways volcanoes erupt?
there lots of diffrent ways slow steady fast .
Where do large number of volcanoes form?
Volcanoes Form at Active Subduction Zones or in the ring of fire
What are four types of volcanoes . examples of the volcanoes?
cone, crater, crown,strato

What are 2 ways to write the the plural form of volcano?
volcanos, volcanoes
How many ways an island can form?
Glaciers, volcanoes, and erosion, explosion, implosion.
What are two Ways volcanoes Form near converging plate boundaries?
Volcanoes may form where two oceanic plates collide or where an oceanic plate collides with a continental plate.
How do volcanoes form in the ring of fire?
Volcanoes can form from other other volcanoes in the ring of fire
How is the way volcanic mountain form different from the way other mountains form .?
Mountains can be formed in a couple of different ways. Different kinds of mountains are formed different ways. There are four different kinds of mountains: Volcanic, erosional, fault-block, and folded. Volcanic mountains, also known as volcanoes, can be standing alone or be part of one big chain of volcanoes. Volcanoes are areas in which lava and magma move to the surface and burst through the crust. Igneous rocks are formed here. Sometimes, hot molten rock spews out of volcanoes. This is earth's way of releasing its internal heat
